It's been a long time since I've posted here - I've been absent from the board, but not the bike. Commuting this summer has been HOT here in N. Texas - lost track of how many 100+ days in a row with the hot wind in my face. All that changed, at least temporarily, yesterday. Greatest ride home in a long time - brand new chain made an amazing difference in shift speed and noise level of the bike, and temps <90 put serious jump in my legs. The result? Same ride time as in the heat, but I felt 100% better when I got there. Ride this morning was <70 - was actually cold for a while on the way in. That was awesome!
